Theophylact of Ohrid, on Heb 12:6

“For whom the Lord loveth, he chastiseth; and he scourgeth every son whom he receiveth.”

“Among those loved by God, one cannot find anyone who would be without sorrows. But are not robbers and thieves also subjected to scourging? Are they then sons? No. For he did not say that everyone who is scourged is a son, but: every son is subjected to scourging. Thus, robbers are scourged not as sons, but are punished as evildoers. Having said here first that He "chastens" (παιδεύει), he then added: "scourges" (μαστιγοῖ) so that you would understand the scourging of a son not in the sense of vengeance for evil, but in the sense of instruction. "Whom He receives," that is, whom He admits to Himself, whom He accepts more frequently in comparison with others, whom He draws near as a close friend.”
